Leonardo DiCaprio and Jonah Hill on a Boat in Sydney

Leonardo DiCaprio and Jonah Hill soaked up the sunshine during a luxurious boat ride on Sydney Harbour on Friday. The Django Unchained co-stars also had the company of Hollywood friends Lukas Haas and Kevin Connolly, and spent the day partying with bikini-clad women as they made their way to The Island. Earlier in the day they arrived on a private jet with Jamie Foxx, which was reportedly organised by The Star, where the celebrities will be spending New Year's Eve tonight. They'll join a host of other announced stars including Chace Crawford, Matthew Morrison, Colton Haynes and Samantha Ronson, who will all be making appearances at Marquee.

It seems that Leo, Jonah et al will be very busy on New Year's Eve, with the Sunday Telegraph reporting that they'll be flown back to Las Vegas straight after the midnight countdown so they can ring in 2013 in the US as well.
